On a Saturday, I walked from the Monte Carlo to the Fashion Show Mall, but I definitely recommend taking The Deuce Bus. For $7 you get unlimited bus travel for 24 Hrs.
This mall has a great selection stores! Some are hard to find in other places and some I have never even seen some of them before. However, branded stores like Neiman Marcus, Macy's and Dillard's had smaller selections than in many malls I have seen.
Something I have noticed in Vegas is that there are a lot kiosks, tons of kiosks selling everything from gold dust facials to electric helicopters. After walking by a hundred of them they can become annoying, but the key is just to avoid eye contact.
The food court shares the same variety as the stores do and I guarantee you'll leave full.
Not a perfect mall, but nothing negative about it.
